html - Firefox flex bug applied to buttons? -


i'm trying apply flex button on firefox i'm having problem on chrome doesn't happens.

this css:

.button {   display: inline-flex;   align-items: center; } 

as can see in fiddle, "caret" word moved new line, happens if element <button> tag, <div> works expected.

is firefox bug or there css i'm missing?

nevermind, looks "mr firefox" doesn't idea...

<button> not implementable (by browsers) in pure css, bit of black box, perspective of css. means don't react in same way e.g. <div> would.

this isn't specific flexbox -- e.g. don't render scrollbars if put "overflow:scroll" on button, , don't render table if put "display:table" on it.

stepping further, isn't specific <button>. consider <fieldset> , <table> have special rendering behavior:
data:text/html,<fieldset style="display:flex"><div>abc</div><div>def</div>
data:text/html,<table style="display:flex"><div>abc</div><div>def</div>

in these cases, chrome agrees , disregards "flex" display mode. (as revealed fact "abc" , "def" end being stacked vertically). fact happen you're expecting on due implementation detail.

in gecko's button implementation, hardcode <button> (and <fieldset>, , <table>) having specific frame class (and hence, specific way of laying out child elements), regardless of "display" property.

if want reliably have children reliably arranged in particular layout mode in cross-browser fashion, best bet use wrapper-div inside button, need inside of <table> or <fieldset>.
